ADJUSTABLE SUPPORT FOR ELITE-CLEANERS.

Specification of Letters Patent.

Application filed April 6, 1911.

Patented Dec. 19, 1911.

Serial No. 619,422.

Be it known that I, CHARLES C. CHAM- BERLIN, a citizen of the UnitedStates, and

a resident of \Vashington, in the county of Washington and State ofPennsylvania, have invented anew and useful Improvement in AdjustableSupports for Flue- Cleaners; and I do hereby declare the following to bea full, clear, and exact description thereof. v

My invention relates to an adjustable support for a boiler-flue cleaner.

The object of my invention is to provide a simple and eflicient form'ofsupport for a boiler-flue cleaner which is particularly adaptable toboilers for field-work, such as the drilling of oil and gas-wells, or inconnection with the boilers of traction-engines for driving threshingmachines,etc.

My invention contemplates the provision of means for adjustably andremovably carrying a rotary flue cleaner of the modern type connected tothe boiler, so that such .a fine cleaner can be swung to and fromoperative position, being out of the way when not in use.

My construction is to be distinguished from prior devices in whichswivel or elbow joints are employed in the steam pipe connected toa'nozzle or flue cleaner adapted to I clean only one flue or tube at atime, the said joints being essentially part of the flue cleaner andnecessary to its operation in cleaning an entire set of fines. By myinvention a complete operative flue cleaner is mounted in removableposition externally of the boiler.

To these ends my preferred construction comprises, generally stated, incombination with a boiler and a steam supply pipe leading therefrom, aswinging support including a pipe section pivotally mounted externallyof the boiler and connected to said steam supply pipe, and a boiler fluecleaner carried thereby preferably in rigid position relative to saidswinging support and steam connected thereto, so that the steam from theboiler passes through the swinging support to the flue cleaner.

In the accompanying drawings, Figure 1 is a View of the portion of thefront end of a boiler of the field-type to which my invention isapplied; Fig. 2 is a front View; Fig. 3 is an enlarged detail of theswivel connection between the support and the steampipe.

In the drawings the numeral 2 designates a portion of a suitable type offield-boiler tained within the coupling 10 which forms a steam-tightjoint and permits of the turning of the swivel meriibers'l. The outerends of the swivel inembers 7 are connectedby the elbows 12 to the pipes13. The outer ends of the pi es 13 have the elbows 14'which engage t einlets 15 of a suitable fluecleaner 16.

The flue-cleaner I have illustrated is what is known as the Barnhillflue-cleaner illustrated and described inUnited States Letters PatentNo. 913,675, and I have not deemed it necessary to illustrate the samein detail, as any suitable form of flue-cleaner may be employed.Generally speaking, however, saidflue-cleaner has the nozzle 17 with theoutlets 18 which'are adapted to be connected up successively with avalve contained Within the flue-blower, so that by turning the rod 19the valve may be 'connected up to any one of the outlets 18.

In order to support the flue-cleaner in raised position when not in use,I employ the hook 20 which may be connected to the pipe 5 as clearlyillustrated in Fig. 1.

When my invention is in use and the fluecleaner is not in operation, itis swung up into the position indicated in Fig. 1 with the hook 20engaging the flue-cleaner, to hold it in its elevated position where itis out of the way, so that access may be had to the boiler for firing orother purposes. lVhen it is desired to clean the fines the hook 20 isreleased and the adjustable support with the flue-cleaner may be swungdown into the position indicated in dotted lines Fig. 1 with the forwardend of the flue-cleaner entering the opening 4 so as to reach the tubesof the boiler. When the flue-cleaner has been lowered to this positionthe same is admitted to the pipe 5 and the steam passes through saidpipe and" the support into thefiue-cleaner whence it is dischar ed bythe nozzle 17 into the flue of the Eoiler to-thoroughly clean the same.When the flue cleaning operation is com.- pleted the supportis swunguickly up out of the way and again engage by the hook 120. In this wayI- provi e a support for a boiler-fiuecleaner s ecially adapted forfield fuse in which the ue-cleaner when not in use is swung up out ofthe way so as not to interfere with the operations around the bo iler.When, however, the flue-cleaner 1s sed, it is readily brought into posiition without having to rig up a support for the flue-cleaner or make anypipe connections. Theswinging joint between the support and the supplypipe. is a practically steamtight constructioncso that there is no lossof steam and the fiuecleaner is'provided with the necessary amount ofsteam to make its work effective.

It is apparent that the swinging support may be swung from the side ofthe boiler instead of from the top' without departing from the spirit ofmy invention.

ing the same to said supply pipe and pivotally carrying the same thereonexternally of said boiler, and a boiler flue cleaner rigidly carried bysaid swinging support and steam connected thereto.

3. The combination with a boiler and a steam supply pipe leadingtherefrom, of a swinging support co'mprismg a pair of pipe sections eachprovided with a pivoted steam joint connection withsaid supply pipe, andeach having inwardly extending elbowsand a boiler flue cleaner carriedby said elbows and steam connected thereto.

4. The combination wit-l1 a boiler'and a steam sup-ply pipe, of aswinging support mounted externally of said boiler and comprising a pairof pipe sect-ions each havin a rotatable steam joint connection with saisupply pipe, and each provided with rigid elbows, and a boilerfluecleaner carried be- ..tween saidv elbows and steam connected.-

thereto.

The combination with a boiler and a steam supply pipe leading therefrom,of swivel members supported on said steam supply pipe and each providedwith a pipe section extending at substantially right angles thereto, andconnecting, with said steam supply pipe through said swivel members, anda boiler flue cleaner carried by said-pipe sections, subst ntially asdescribed.

6. The combination .vith a boiler and a steam supply pipe leadingtherefrom, of swivel members supported on said steam supply pipe andeach provided with a pipe section extending at substantially rightangles thereto, and connecting with said steam supply pipethrough saidswivel members, inlet pipes extending inwardly from said pipe sections,and a boiler flue cleaner carried between said inlet pipes,substantially as described.

7. The combination with a boiler and a steam supply pipe leadingtherefrom, of a swinging snpportincluding a pipe section,

provided with a swivel steam joint 'connect ing the same to said supplypipeand pivot ally carrying the same thereon externally of said boiler,a boiler ,flue cleaner rigidly carried by said swinging support andsteam connected thereto, and means for holding said flue cleaner inraised position when not in use.

8. 'lhe'conibination with'a boiler and a steam supply pipe connectedthereto,- of'a swinging support comprising pipe sections connected byswivel joints, to sai steam pipe, and supported thereon enternhlly ofsaid holler, a flue cleaner-carried Ibjfs'aid pipe sections and steamconnected thereto,

and means for holding said swinging support in removedposition,substantially as described. 4

In testimony whereof, I the said CHARLES C. Cnaanmnux have hereuntosetmy hand.
